Confidence score

A numerical value (typically 0-100% or 0-1) indicating how certain an AI system is about its prediction or classification. In accessibility contexts, communicating confidence scores to users — particularly blind users who cannot visually verify AI output — helps them calibrate trust and decide when to seek additional verification. Low confidence scores signal that a recognition may be unreliable, while high scores suggest greater certainty. Effective confidence communication must be accessible (not just visual) and presented in a way that is meaningful to non-technical users.
